Application led September. 6, 1923. Serial No. 661,147.

In the operation of dry cleaners, one well known orm of which comprises a washer for receiving the cleaning liquid (e. g. gasoline,) and within which the clothes are washed, a centrifugal clarifier, a pipe line 'from the washer to the clarifier and 4back to the washer, and a pump to maintain the circulation of cleaning liquid, it is customary to interpose a strainer in the pipe line between the Washer andthe lpump and clarier, to preventA the passage'of buttons, lint and other similar products that would obstruct the action of the pump or clog the clarifier. My invention is more particularly intended for use as such `a strainer, although it is adapted for use in any apparatus in which a straining operation is required 'or desired.

In the drawings, which show a preferred embodiment of the invention:

Fig. 1 is a sectional elevation of the strainer.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Fig. 3'is an end view, partlybroken away, of the lower part of the strainer, looking toward the rear. l

The base of the strainer is a casting comprising a bottom carrying a supporting flange legs c, c at the front, the bottom thusbeing y supported so as to slope downward from front to rear. The base, at the front, has an entrance nozzle d. At the rear, the base has an upright f supporting a discharge nozzle e. These two'nozzles are on the same level', and are Vrespectively connected with' the two sections, g, g', ofthe pipe line, it being desirable to have the two sections ot the pipe line leading tothe pump on the same level. The ange falso vcarries .a drainage and cleaning outlet, normally closed by a plug h. The shell i of the strainer rests on the base a, itsfront and rear walls having openings registering with the nozzles e and d. in. the. shell i extends a series of screens c, m,.and n y -parallel with-the front and rearwalls of the shell z'. These screens comprise lates rovide'dwith a mullplicityof sm perorationsash'i screens are-.suppe bersm 'tion g lngr'ooves 1n mem p slired the side wallsof the shell Fig. 2). From' the lower edge of b at the rear and flanged supporting With- @which are arranged vertically, and mg screen extends an upturned flange 1- adapted to rest on the bottom of the shell.

It is preferred to provide a relatively wide space in :front of the front screen k, and to space the remaining screens apart at uniform distances. However, the number of `screens and their relative spacing may bevaried.

The shell 'i is provided with a removable top j. The screens Apreferably extend almost to the top of the strainer. The strainer should be so positioned relatively to the washing drum (not shown) that the gasoline level in the washing drum will be just, belowthe upper ends of the screens.

In case any solid materials of the character hereinbefore fmentioned enter the strainer, the will be arrested thereby, and sink down into the 'crotch of one of the screens. Most of such materials, and all large sized solid material, such as buttons,

will not pass the first screen, wherefore it is preferred to provide a relatively wide space lin front of the front screen k.

From time to time, and, if desired, during the operation of the washer andthe How of liquid through' the strainer, the screensfmay be removed, one at a time, cleaned, and replaced. During the removal of the front screen 7c, for example, the next screen, m, will act asthe primary screen.

It is impracticable, or at least undesirable, to make the entire strainer of heavy material; but by making form of a heavy rigid castlng, the whole contrivance'is rendered suiiiciently -staunch to resist wear and tear. I v l Having now fully described my invention, what I'claim and desire to protect by Letters Patent is:

1.* A strainer 'of the character described comprising .a shell having imperforate side walls, front and -rear walls provided respectively with liquid admission-and discharge orifices, and an imperforate bottomslo ing from front to rear; a removable screen ava perforated vertical member and an imperforate iiane extending at an acute angle the A an tom'; and ase aratenoz su porting mem-v ber andno 'escarriedthereyr'egistermg withsaidorifces.

.2. A strainer of the-character 'described Acomprising a shell having an-inlet in its the 'base in the on the shell bot-v front wall and an outlet in its rear wall and a bottom sloping from 'front to rearxand independently removable elements each comgrising a vertical extending screening memer and a flange extending at an acute angle thereto and vresting on the sloping shell bottom, each of said flanges except the one on the front screen substantially covering that part of the shell bottom between the screen from which it extends and the next adjacent screen in front.

3. A/strainer vof the character described comprising a shell having an inlet in its front Wall and an outlet in its rear Wall and a bottom'sloping from front to rear, and independently removable elements each comprising a vertically extending .screening member and a ange extendin at an angle thereto and resting on the sloping shell bottom, each of said flanges except the one on the frontscreen substantially covering Athat part of: the shell bottom between the screen from which it extends and the next adjacent screen in front, the flange on the front screen substantially covering that part of the shell bottom between the front screen and the front Wall of the shell. n

In testimony of which invention, I have hereunto set my hand, at New York, on this 4 24th day of August, 1923.
